%X We investigated the relationships between neutrophil function measured using the nitroblue tetrazolium (NBT) reduction test and measurements of psychological stress and life events among 81 men aged over 60£¿years.The numbers and scores for life events were significantly higher (p£¿<£¿0.01, respectively) in a group with values reflecting phagocytosis below the median than in a control group.Chronic psychological stress due to life events decreases neutrophil functions among elderly men.
